I've set the playtest build of Lylian for end of October. Basically a vertical slice of the game.
A couple of people have already had an early play over the past month and the responses and feedback have been awesome. Some of the major mechanics hadn't even been implemented yet, so it makes those responses doubly awesome.
If you'd like to participate in the next playtest; please sign up to the Lylian newsletter, and/or facebook page. I'll only be taking on a small number of interested peeps for this one, but there'll be more to come in the future too.
